Abstract
A marine transport screw fastener comprises a socket base, an elephant foot, a chain ring, a left screw U-shaped rod, a thread sleeve, a right screw C-shaped rod, a handle, a ratchet, a pawl, a long link chain and an upper connecting piece. A cruciform slot is disposed on the socket base. A square-shaped bottom plate of the socket base and an upper cover of the socket base are integrated into one piece through welding. A circular card at the lower part of the elephant foot cooperates with and stably clamps with the cruciform slot of socket base, and the upper part of the elephant foot is a Y-shaped structure with a crotch being connected to the long link chain through a pivot pin. One end of the left screw U-shaped rod is a Y-shaped structure with a notch being provided with a pivot pin and connected to the long link chain, and the other end is threaded and is in a threaded connection with the thread sleeve. One end of the right screw C-shaped rod is threaded and is in a threaded connection with the thread sleeve, and the other end is a C-shaped hook connected to the long link chain through hooking. The C-shaped hook is provided with a spring clip, preventing the long link chain from slipping. The external part of the thread sleeve adopts a bidirectional ratchet and pawl structure which can rotate in a clockwise or anti-clockwise manner. The handle can rotate 90 DEG around a handle pin. The tail end of the chain is the upper connecting piece comprising a long hooking ring, a short hooking ring and a shackle.
Description
Technical field
The utility model relates to a kind of sea-freight screw-tightened device of goods transport.Be applicable to that the boats and ships seat transport is wheeled, the heavy shape mechanical equipment of crawler type and other goods be solid binding.
Background technology
At present, in the middle of China's ship industry, the binding of wheel car or heavy shape tank and other items transportation is reinforced, generally adopt syntheticfibres fastener, steel rope, lever chain fastener system admittedly.Syntheticfibres fastener maximum securing load is 100KN, and heat-resisting quantity is poor, is applicable to the light shape equipment of binding reinforcing.Shortcomings such as the lever fastener exists safety factor low, and the tension fixed distance is finely tuned the distance weak point, and it is big to take up room.The intensity height of steel rope, cost are low, but are easy to disconnected strand, exist bigger potential safety hazard as the standard equipment repeated use.In the civil transport field, steel rope generally uses as disposable reinforcing equipment.
Summary of the invention
The purpose of this utility model is to provide a kind of intensity height, and is simple to operate, the fine setting distance, and it is little to take up room, economical and practical, the safe and reliable and reusable spiral chain fastener of energy.It has overcome the deficiencies in the prior art.
The technical solution adopted in the utility model is: sea-freight screw-tightened device by the nest seat, resemble pin, chain link, left-hand screw U-shaped bar, swivel nut, right-hand screw C shape bar, handle, ratchet, ratchet, long-link chain, upper connector etc. and form.Described nest seat is made of nest seat loam cake and nest seat base plate, and nest seat loam cake is bent into square, is provided with cross recess, and nest seat base plate is square integrally welded with nest seat loam cake.The described underfooting portion that resembles is match with nest seat cross recess card jail of circular card, and top becomes " Y " shape structure, in its prong pivot pin is housed, and is connected with chain link by pivot pin.Described left-hand screw U-shaped bar one end becomes " Y " shape structure, in its prong pivot pin is housed, and is connected with chain link by pivot pin, and the other end is provided with Acme thread, and its screw thread is threaded with swivel nut.Described right-hand screw C shape bar one end is provided with Acme thread, and its screw thread is threaded with swivel nut, and the other end is used for colluding the extension long-link chain for C shape hook, adjusts the solid length of long-link chain system rapidly on a large scale, on the C shape hook Spring Card is arranged, and prevents the long-link chain slippage.Described swivel nut is a tubular structure, an inner end is that right-hand screw thread matches with left-hand screw U-shaped bar and right-hand screw C shape bar respectively for the minus thread other end, play the effect of the solid chain of fine setting tension system, the two-way click structure of its outside employing, can positive and negatively rotate, the chain of straining or get loose, its described handle can be around 90 ° of rotations of lever pin.Described chain is a long-link chain, and the chain end is a upper connector, and described upper connector comprises that length articulates ring, weak point articulates ring, shackle.
Described handle is installed on the handle set, can be around 90 ° of rotations of lever pin.
Described handle set becomes " Y " shape structure, and front end is circular hollow, is enclosed within fastening screw and puts, and the center, rear end is provided with a blind hole, and ball and spring are installed.
The ratchet of described two-way click structure is the two-way right-angle structures of two pawls.
The present invention adopts said structure, can all be made of metal, and compared with prior art has the following advantages: having overcome the syntheticfibres fastener can not resistant to elevated temperatures shortcoming, has overcome the shortcoming of the easy fracture of wire of steel rope disconnected strand simultaneously.On self advantage, simple in structure, easy to use, but partial disassembly repair, reusable.Arrange the nest seat according to actual needs, the alerting ability height uses the solid equipment quantity of system few, and actv. utilizes the cabin capacity, has improved economic benefit.The present invention will link up with and the screw rod unit design, the needs of quick adjustment chain length have been satisfied, make compact overall structure again, adopting long-link chain to make the dragline rope compares with other chains, alleviated weight, reduce labour intensity, adopted the screw-tightened structure to play the effect that chain is strained in fine setting, laborsaving convenience.
